A connection structure between a shaft and a clutch

Abstract

The invention discloses a connective structure of a shaft and a clutch. The connective structure comprises a shaft (1) and a clutch (2), wherein the clutch (2) comprises a connecting shaft sleeve (2a) connected with the shaft (1), and an inner hole of the connecting shaft sleeve (2a) is provided with a penetrating groove (2b) the cross-sectional shape of which is rectangular along the axial direction of the connecting shaft sleeve (2a); a short key (2c) is embedded into the penetrating groove (2b), and bolted connection fixation is adopted between the connecting shaft sleeve (2a) and the short key (2c); the shaft (1) comprises a shaft head part (1a), a connecting part (1b) and a shaft root part (1c), and the shapes and sizes of the shaft head part (1a) and the shaft root part (1c) are coincident with each other; and the shape of the connecting part (1b) is similar to the shape of a hole (3) formed by the inner hole of the connecting shaft sleeve (2a) and the short key (2c). The connective structure provided by the invention has the advantages that the structure is simple and reasonable, a shaft head is effectively prevented from being thinned, and thus, the mechanical strength of the shaft head part is ensured.

Description

technical field [0001] The invention belongs to a connection structure, in particular to a connection structure between a shaft and a clutch. Background technique [0002] At present, when the clutch is connected to the shaft, the shaft head is usually thinned, and then the shaft head is inserted into the inner hole of the clutch shaft sleeve, but in some special occasions, the shaft needs to be inserted after passing through the inner hole of the shaft sleeve in the clutch. It is connected with some components, but the shaft head is thinned due to the connection structure between the clutch and the shaft in the prior art, thereby weakening the mechanical properties of the shaft head. Contents of the invention [0003] The object of the present invention is to overcome the disadvantages of the prior art, and provide a connection structure between the shaft and the clutch which makes the shaft head unnecessary to be thinned. [0004] In order to solve the problems of the t...
